Olivier L. de Weck (born 1968) is the Apollo Program Professor of Astronautics and Engineering Systems at the Massachusetts Institute of Technology (MIT).^[1] He has authored and co-authored more than 400 peer-reviewed publications. He is a Fellow of the INCOSE and a Fellow of the AIAA.^[2][3] He is the Editor-in-Chief of the Journal of Spacecraft and Rockets.^[4] From 2013-2018 de Weck served as the Editor-in-Chief for Systems Engineering, the leading journal of INCOSE.^[5] He is best known for contributions to the fields of Systems Engineering, Design optimization, and Space Logistics, where together with colleagues from JPL he coined the term Interplanetary Supply Chain. More recently he has become active in the field of Remote Sensing.

de Weck earned a Dipl. Ing. degree in Industrial Engineering from ETH Zurich in 1993. Between 1993 and 1997 he worked as a liaison engineer and engineering program manager on the Swiss F/A-18 fighter aircraft program in St. Louis, MO. He earned both a S.M. degree in Aeronautics and Astronautics in 1999 and a Ph.D. in Aerospace Systems in 2001 from MIT.^[1] His doctoral dissertation titled "Multivariable isoperformance methodology for precision opto-mechanical systems" was supervised by David W. Miller who served as NASA's Chief Technologist.^[6][7]

de Weck joined the MIT faculty in 2001 where he has a dual appointment with the Department of Aeronautics and Astronautics and the Institute for Data, Systems, and Society (IDSS). He previously served on the National Research Council Committee on Cost Growth in NASA Earth and Space Science Missions (2009–2010) and as the Executive Director of the MIT Production in the Innovation Economy (PIE) Study (2010–2013).^[8][9] Between 2011-2016 he served as the co-director of the Center for Complex Engineering Systems at KACST and MIT.^[10] As of 2015^[update] he serves as the faculty director of the MIT-Switzerland program.^[11]

de Weck leads the Strategic Engineering Research Group in the MIT Engineering Systems Laboratory which emphasizes "the process of architecting and designing complex systems and products in a way that deliberately accounts for future uncertainty and context in order to maximize their lifecycle value."^[12] Past research has been sponsored by organizations such as NASA, DARPA, Xerox, and BP.

de Weck developed or supervised development of a number of methods and tools including:

• Isoperformance method to find performance-invariant designs^[6][13]
• Adaptive Weighted Sum (AWS) method to find equidistant Pareto optimal solutions^[14][15]
• Delta Design Structure Matrix (ΔDSM) to quantify the impact of new technology on an underlying system^[16]
• Time Expanded Decision Networks to make decisions under uncertainty^[17][18][19]
• Generalized Multi-commodity Network Flows (GMCNF) to find optimal resource routing through geospatially distributed infrastructure^[20][21][22]
• SpaceNet space logistics discrete event simulation software^[23]

From 2017-2018 de Weck took a two-year professional leave of absence from MIT to serve as the Senior Vice President for Technology Planning and Roadmapping at Airbus in Toulouse, France.^[24] His recent research focuses on long term Technology Planning and Roadmapping.
